<ScrollView android:layout_width="fill_parent" android:id="@+id/scrollView1"
android:layout_height="fill_parent">
<LinearLayout android:id="@+id/linearLayout1"
android:layout_width="fill_parent" android:orientation="vertical"
android:layout_height="fill_parent">
<ListView android:id="@+id/listView1" android:layout_width="fill_parent"
android:layout_height="fill_parent"></ListView>
</LinearLayout>
</ScrollView>
ScrollView填满整个屏幕,但LinearLayout1只填满屏幕的一小部分,大约高度为100dip。如何使LinearLayout1填满父容器?
